Specification of Letters Patent.

Patented. dune 4:, 1907.

Application filed April 3,1906. Serial No. 309,681.

T0 (ZZZ whom it may concern:

Be it known that we, JAMES D. MINTO and JAMES KELLY, citizens of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Air Cooling and Humidityof which the following is a specification.

This invention relates to certain new and useful improvements in air cooling and humidifying apparatus and is an improvementin the type of such devices as is shown and claimed in prior patent No. 787,454 issued April 18, 1905, and also the type shown and described in application filed by James Kelly September 15, 1905, Serial No. 278,651.

The present invention has for its object to provide a device or apparatus of the character stated by means of which a perfect discharge of either a hot or cold vapor from the distributer or atomizer may be efiected.

A further object of the present invention is to provide a device in which the drip-pipes ordinarily employed in devices for the same purpose, are entirely dispensed with, and in wnich the supply pipes utilized may be of much smaller diameter than is required with the majority of devices employed for similar purposes.

A still further object of the present invention is to provide a device in which a constant supply of pure water is assured, as well as a constant supply of fresh air, and in which the supply map be readily and easily regulated and contro led as desired;

The device forming the subject matter of this application is adapted for cooling the air of apartments and buildings, and is especially adapted for therooms of mills having textile machinery, as in such rooms, the air is liable to become very dr or full of dust of fibers in consequence of tie operation of the machinery or the employment of manufactur ing processes, which are detrimental to the health or comfort of the workmen, and while the device is particularly adapted and designed for such use, it is equally adapted for use in other relations, such for instances as in hospitals and the like.

In the accom anying drawings forming a part of this app ication, we show a ractical embodiment oi the invention as it as been practiced by us, and in the following description, will have reference thereto, like letters indicating like parts throughout the different views, it being understood however, that while a practical and referable embodiment of the invention is s own and will be described, we do not desire to limit ourselves to specific details of construction shown.

In the said drawings: Figure 1, is a perspective view of an air cooling and humldlfymg apparatus constructed in accordance with our-invention, diagrammatically illustrating the manner in which sameis arranged ma room or apartment. Fig. 2, is an enlarged central vertical sectional view of the distributer or atomizerl Fig. 3, is a cross sect onal view thereof, taken on the line of Fig. 2. Fig. 4, is a similar view taken on the line 'yy of Fig. 2.

As heretoforestated, we ainrin the pres ent invention to obviate the use of all dr p pipes which are exceedingly objectionable 1n mills and the like, as they interfere with the machinery, belting etc., especially if the celling is low, and again, it is important and essential in most mills that as little space as possible be occupied by subsidiary devices such as humidifiers, the available space being required for the perfect working of the machinery.

We have designated the showing 1n Fig. 1,

as a diagrammatical one, it being understoodthat the blower A, is located at any desirable or convenient point, and being of a conventional form having the usual alr-lnlet 1), airchamber .0, and relief-valve d. ,Comrnumeating with the air-chamber c, is a pipe e,

which is extended upwardly and connectedto the air-pipe e, which in practice is generally located near to the ceiling, and approximately centrally oi the room, and has connected thereto a branch e, which carries or is in communication with the'improved vapor-distributer or atomizer f. g, is a pipe adapted to receive hot or cold water under pressure, and this pipe 1s also generally located close to the ceiling, substantially parallel with" the air-pipe e as shown.

his plpe g, communicates through branches 9, g with the air-pipe, the branches 9", and

- e of said pipes being connected at point it,

generally by a three-way union or coupling as shown. in the water-pi e, we also provide a water-valve i, genera 1y located at the juncture of the branches g, 9 as shown.

. said receptacle adapted to receive member f The air-pipe is provided with a shut-off cock and the water-pipe is provided with a simi ar shut-off cock 9", am these are generally located in the branches g, and e of said pipes respectively. These cocks are 0 ened and closed simultaneously by means 0 links connecting them, and a hand-operating rod k as shown, or other equivalent means. It is to be understood that we do not limit ourselves to the specific arrangement of the pipes as shown and described, orto .the location ofthe shut-off cocks, as this may be altered at will to suit the conditions of the room in whichthe device is erected, without in any manner departing from thescope or spirit of the invention.

The vapor-distributer or vaporizer f comrises two members f and f as shown in ig. 2. The upper member f 2 threads into, or is otherwise suitably joined to the deending. branch of the coupling or union it.

his member f is rovided approximately.

midway of its lengt 1 with an interior or internal nut f provided with one or more ports or assage-ways f for the passage of the liqui -moisture. The lower member f is provided with a stem f 5 which threads into said internal-nut f 3 oi the member f so that the said members f, and f 2 are thereby adjustably-connected together, and regulation of the discharge of vapor from the va orizer or vapor-distributer is thereby readi y efiected.

The memberf' of the vapor-distributer or atomizer is concavedon the upper face of its head, around the stem f substantially forming an annular valve-member f 0 around the perimeter of said head, which valve-member co-acts with the annular valve-member f 7 on the lower face of the head or lower end of the By turning the member f toward or away from the member f, it will be readily seen that the space between the two annular valve-members or faces is increased or decreased and the discharge of the va or' correspondingly increased or diminishe The member f has its bottom closed, and by this construction a receptacle f B is formed, an of the liquid which has for any reason'not become sub'ected to the atomizing process.

he operation of the device will, it is believed, be clearly evident to those skilled in the art, from the foregoing description, taken in connection with the accompanying drawings, as it will be evident that the air passing through air-pipe e and the Water passing through pipe g are brought together and comingled at point h, and discharged in the form of a spray throu h the vapor-distributeror atomizer f, the ischarge of this spray being controlled as afore described by the adjustment of the lower member-fof the ply, comprising seems distributer or atomizer is located, which,

combined with the fresh water, effects the best results obtainable,and by regulating the water supply, the spray can bemade either heavy or fine as may be desired for the conditions existing in the room. It is to be observed also, that with the construction shown and described it is impossible for any foreign particles or matter with which the air in the mill-room may be charged to get into the air-pipe or-wateripe, and thus hinder the' roper working 0 the device. By the emp oyment of two valves, it is to be observed that we set one to regulate the supply as desired, and employ the other to shut off the atomizer when not in use. The chamber f in the member f of the distributer or vaporizer serves to catch any liquid that may not be discharged in the form of spray, and this drip-cup may be readily drained by removing the member f sar fiaving fully described our invention, what we claim as new and desire to secure by Letters Patent is I 1. In a humidifying apparatus, an air supply and a communicating water supply,

means for controlling said air supply and water su ply, a distributer communicating with hot the air supply and the water suptwo, members disposed in ongitudinal alinernent and with their adjacent faces slightly spaced apart and one of said members having, a screw-threaded projecting shank adapted to engage a perforated nut in the interior of the other of said members substantially as described.

2. The combination with a water and air supply, of an atomizer comprising two tubular members, havin enlarged contiguous ends with opposed s ightly separated faces, one of said members having its one end closed and its other end perforated and provided with a bevel face, a screa-threaded shank projecting centrally from said bevel face, a perforated nut carried by the interior of the other of said members, said screw-threaded shank adapted to engage with said perforated nut, thereby forming means by which the two members of said atomizer are adjust-' abl secured together. 1
